Abstract
The problem of determining theP-waveπ-π phase-shifts given the modulus of the electromagnetic form-factor in the time-like momentum transfer region has been discussed. The problem ofK 01 −K 02 mass difference has been discussed with emphasis on the scalar form-factor rather than models ofπ -π scattering.
